Unlocking iPhone means you can use your iPhone with a different carrier. In the US, UK or Australia, unlocking is sometimes referred to as contract-free or SIM-Free phone. The easiest way to unlock an iPhone is to go through your carrier. Once your carrier unlocked your iPhone, you can back up and restore your iPhone to unlock it immediately. Often, you can only request an unlock from your carrier when your are not tied up to any contract. In other words, you have to meet the requirements to unlock your iPhone. This usually doesn’t happen to people who have just bought an iPhone through a carrier network with monthly installment or people who don’t pay the full price for their iPhone. There are, however, a few third party methods to unlock an iPhone.

Software to Unlock iPhone
